List of top Physics Questions on Waves asked in MHT CET

A sound wave has a frequency of $ 440 \, \text{Hz} $. What is its time period?
A sound wave travels through air with a frequency of 500 Hz and a wavelength of 0.68 m. Calculate the speed of sound in air.
The frequency of a wave is 50 Hz, and its wavelength is 2 m. What is the speed of the wave?
How much time does a particle at \( x = C \) take to go from the mean position to the extreme (maximum displacement) for the first time?
A particle on a string undergoes a transverse wave motion given by: \[ y = 5 \sin \left( 4 \pi t - \frac{\pi x}{2} \right) \] (All quantities in SI units.) How much time does a particle at \( x = 0 \) take to go from mean position to extreme (maximum displacement) for the first time?
The speed of a wave is \( 30 \, \mathrm{m/s} \). If the distance between 11 crests is \( 1 \, \mathrm{m} \), what is the frequency (in Hz)?
A closed organ pipe (closed at one end) is excited to support the third overtone. It is found that air in the pipe has:
The velocity of sound in a gas in which two wavelengths \( 4.08 \, \text{m} \) and \( 4.16 \, \text{m} \) produce 40 beats in 12 seconds will be:
A steel wire with mass per unit length \( 7.0 \times 10^{-3} \, \text{kg/m} \) is under a tension of \( 70 \, \text{N} \). The speed of transverse waves in the wire will be:
